In the field of computer music research the development of new input devices for musical performance and sound interaction plays an important role. This paper explores the cultural implications embedded in the use and concept of the notion of the instrument in such fields. Cultural implications in this particular context are the meaning structures that evolve from knowledge expressed through language and developed through practices. The main focus of this inquiry is based on the potential to detect the impact of new computer music research on its socio-cultural environment. Concepts such as assemblage and ecology will propose alternative ways to address the hybrid relational (interdisciplinary) networks that create such input devices. This approach proposes alternative models to conceptualize interaction as performative relations between humans and nonhumans, as outlined in the domain of Science and Technology Studies. Computer research interweaves the cultural dimensions with a social context and foregrounds the political implications signified by its practices and technologies.
